My FF5 moment would be when Gilgamesh does that thing at the end. The 'last' thing.

Some other ones I can think of would be:- Yakuza 4's last multi epic fight with the small talks in-between- Charging a 100% Replekia Ar Tonelico with Synchronicity Chain in Ar Tonelico 2- The end of almost every Pheonix Wright's case when Pheonix's theme starts playing and you're demolishing the prosecution- The Vascillia Sky level in ZoE2 makes you feel really awesome- Whenever you fire Maria's Energy Burst in Star Ocean 3. One of the most awesome move I've seen in an RPG

Castlevania Lords of Shadow would definitely deserve a spot on the list for the titan fights. Towering monstrosities, each one larger than the last. The badass moment however,isnthe stance you take when you stare down these pricks, camera angle pointing upward from behind you looking up and all you see is Gabriel Belmont, ready to wreck face. Can't find the photo I most want, but here's the second titan you fight.

The first time the third colossus raises its sword to strike you down in shadow of the colossus was totally badass. The moment is even better if Wander has been tossed to the side and struggling to get up as the sword falls, although it is more a moment of panic than badassery then.

I was not a big fan of the story mode in Soul Calibur 3, much preferring Chronicles of the Sword but a quote from one of the last bosses on an evil character's route was totally badass

Just about any action scene involving Id during the 1st half of Xenogears

I'll do one better and specifically mention the battle in the desert where he shows up and Bart tries to get clever and runs him over with his sand submarine. Too bad he only succeeded in pissing him off.

Also just remembered Cornelius from Odin's Sphere and his awesome ability to turn himself into a hopping, whirling, bunny buzzsaw of doom. Too bad it really wasn't that useful in practice (not like it would've helped his end game much anyways what with all the fucking wizards everywhere).
